A URN is the unique reference number you receive when you purchase a Day 2 test. When you receive your URN from us, you will need to use this number on your passenger locator form when returning to the UK from abroad. Each URN is unique to each customer and cannot be duplicated. Retain this number for when you perform the test as it will need to be captured on our our online portal when completed the registration form.
The URN number is reported to Public Health England on sale of a test and included when we upload your results to Public Health England after performing the test.
